PARIS BAR- a citizen of the United States, resid.

of Cool; and State oflllinois, have inventeda new and usefulGar-Wheel-Balancing Machine, of which the following is a specification."

My invention relates to that class ct niachines constructed for thepurpose of indicating the amount that a given hody is out ct balancewhen such body is suspended from a revolving center or niandrel- Lattainthe Oh- Be it known that I, WILLEAM CLAY,

Fig. i} is a detailview, to an. enlarged scale, of the friction-wheels J and L, meshingwith each other, and showing the location of a spring tupon thefriction-Wheel L. Fig. t is a longiof the mandrel E, showing location offriction- Wheel J and lever'K and sleeve G.- upon the mandrel whenlocated in the bore of a carwheel.

The standards 13 at their top endshave each two circular hearings, into which take the spindles (J of thecarrying from their spindles O as an axis, and are situated in pairs,one pair with the other, so that the peripheries of said wheels form arevolving bearing for a mandrel or shaft, so that when a shaft ormandrel is situated above and upon the peripheries of thecarrying-wheels and turned around 'the said mandrel or shaft of saidcarrying-wheels.- The mandrelE is correspond mandrel E,

The middle or central part ofsleeve .Gjas shod-hie. section in Fig. l, is less in dianieter'than atthe ends of sleeve, and upon the smaller part of sleeve G are placed scveral rubber rings a", that assist to keep the several sections of sleevetogether when. it is taken oil or placed upon the main drel E.
